Specification of Letters Patent.

Patented July 12, 1921.

Application filed October 30, 1918. Serial No. 260,248.

To all whom it may concern Be it known that I, WILFRID J. GIRARD, a citizen of the United States, residin in the city and county of San Francisco, tate of California, have invented certain new and useful Improvements in Continuous Rails, whereof the following is a specification.

This invention relates to continuous rails for railways. In carrying out the invention I construct a rail of a plurality of longitudinal sections. These sections are constructed to interlock together and into the holding chairs in such manner that when a fastening key is inserted, the rail sections, and the chairs, are immovably locked together.

As this form of rail has speclal utility in connection with concrete ties, owing to the strain and vibration being more per fectly distributed, I consider its use with a concrete tie as a part of the invention.

In the accompanying one sheet of drawing I have illustrated my continuous rail in connection with the holding chair and with concrete ties, to-wit:-

Figure 1 is a perspective view of a railway track containing the invention.

Fig. 2 is a cross-section through the rail and a chair showing the fastening means.

Fig. 3 is a partial section, showing the means for securing the chair to the tie.

The ties 1 may be laid and spaced in the same manner as other ties, upon the road bed 2.

Upon the ties, either at every tie or at desirable intervals, are adjustably secured the chairs 8, by means of elongated slots and bolts 4, which may bedded in the material oi the tie.

The chairs comprise the base and flange portion 5, the upright portions 6, one of said uprights having a groove or equivalent locking means 7 and the opposite portion 6 having a set screw 8. 1

In the form shown the rail is composed of three sections 9, 10 and 11 overlapping each groove 16 in its opposite side.

longitudinal groove14 in the section. The lntermediate section 10, has a bead 15, to engage groove 14 of section 9, and has also a Section 11 has a similar bead 17 to engage groove 16, and its outer top edge may be rounded, as at 18 the adjacent inner edges of the sections being square, to provide a flush top with the rail 10. The sections of rail, as thus constructed, when juxtaposed and placed in the chair do not quite fill the space, between the uprights 6 and 6 of the chair, but leave a space, as seen. This space is filled by a key 19, so that when the key is in place the rail sections are firmly held and cannot be withdrawn until the key is first taken out. The key 19 may be effectively retained in place by the set screw 8.

Having thus described my invention, and an embodiment of it, in the full, clear and exact terms required by law, and knowing that it comprises novel, useful and valuable improvements" in the art to which it pertains, I here state that I do not wish to be limited to the precise construction and arrangement of the several parts, as herein set forth, as the same may be variously modified by a skilled mechanic without departing from the spirit of the invention.

What I claim and desire to secure by Letters Patent of the United States, is the fol lorwin to-wit:

1. rail comprising a plurality of longitudinal sections of corresponding width having engaging means therebetween, and a holding chair provided with a removable key for locking said sections together.

2. A rail comprising a series of longitudinal sections tongue-and-grooved together, in combination with a chair having a corresponding groove to engage the ton e of one of said sections, and a key to maintain the engagement of the sections with each other and with the chair.

3. A rail comprising a plurality of longitudinal sections of corresponding width and overlapping each other longitudinally to break joints, said sections being provided with interlocking means therebetween, in combination with a chair having corresponding interlocking means engaging one of said sections and a key to maintain said engage- In testimony that I claim the foregoing I ment. g have hereto set my hand this 22nd day of 4.
